Please answer asap. Will mark brainliest!!!

I started this and got distracted and never finished and it timed out. Focus Dean.

It's not the best graph; I assume the origin is the apparent origin and the y axis numbers go with the line above them.

This graph is M(V), M(V) is mass in kg of bucket with water volume V in liters

a) the mass of an empty bucket

That's the y intercept, M(0), eyeballing it around .7 kg

Answer: .7 kg

b) the mass of the bucket containing 1 liter of liquid

That's M(1), looks like 1.3 or so

Answer: 1.3 kg

c) the mass of one liter of liquid

That's the difference, M(1)-M(0), about .6 kg. We can get a better estimate from a longer slope, say (.5,1) to (3,3), (3-1)/(3-.5) = .8 kg.

Answer : 0.8 kg

d) the volume of the liquid in the bucket, if the total mass of bucket with the liquid is 3 kg.

Solve M(V)=3

That has a solution from the graph V=3.

Answer: 3 liters

What is -2<img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D" id="TexFormula1" title="\frac{1}{2}" alt="\frac{1}{2}" align=

well, you already know how to convert from mixed to improper, so let's simply do the division.

$\bf -2\frac{1}{2}\div 6\implies -\cfrac{5}{2}\div 6\implies \cfrac{-5}{2}\div \cfrac{6}{1}\implies \cfrac{-5}{2}\cdot \cfrac{1}{6}\implies -\cfrac{5}{12}$

Choose the equivalent system of linear equations that will produce the same solution as the one given below. (1 point) 4x − 2y =

goldenfox [79]

Answer:

<h3>Option d) 4x + 2y = 10 and 8x = 16 is correct</h3><h3>Therefore 4x + 2y = 10 and 8x = 16 equations have equivalent solution (2,1) is same as the solution of given linear system of equations</h3>

Step-by-step explanation:

Given equations are

$4x-2y=6\hfill (1)$

$2x+y=5\hfill (2)$

<h3>To find the the equivalent system of linear equations that will produce the same solution as for the given equation :</h3>

First find the solution to the given system of equations by elimination method

Multiply the equation (2) into 2 we get

$4x+2y=10\hfill (3)$

Now adding the equations (1) and ( 3) we get

$4x-2y=6$

$4x+2y=10$

_______________

$8x=16$

$x=\frac{16}{8}$

x=2

Therefore the value of x is 2

Substitute the value of x in equation (1) we get

$4(2)-2y=6$

$8-2y=6$

$-2y=6-8$

$-2y=-2$

$y=\frac{-2}{-2}$

y=1

Therefore the value of y is 1

Therefore the solution to the given system of equations is (2,1)

<h3>Now to find the equivalent system of equations have same solution (2,1)</h3>

Verify the equations $4x+2y=10\hfill (4)$ and 8x = 16

From 8x=16

$x=\frac{16}{8}$

x=2

Therefore the value of x is 2

Substitute x=2 in equation (4) we get

4(2)+2y=10

8+2y=10

2y=10-8

2y=2

$y=\frac{2}{2}$

y=1

Therefore the value of y is 1

Therefore the solution is (2,1)

<h3>Therefore option d) 4x + 2y = 10 and 8x = 16 equations have equivalent solution (2,1) is same as the solution of given linear system of equations </h3>
